"Out of the box" install, and can't send email. Changed in admin to "smtp" and just a email-adress in the "from" field. (Found theese two in other post here)Edit 3 files named php.ini, and replaced "localhost" with smtp.myisp.com (with an actuall adress ofcourse) php.ini found and editet from thise path:c:/xampp/apache/binc:/xampp/phpc:/xampp/php/php4

This is the error I get when a customer buy something, and do the checkout, and if I try to send email to a customer from admin:

Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\xampp\htdocs\catalog\admin\includes\classes\email.php on line 520
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\catalog\admin\includes\classes\email.php:520) in C:\xampp\htdocs\catalog\admin\includes\functions\general.php on line 22

I'm not certain the SMTP based email works out of the box (I never tried to get it working out of the box). The sendmail based email does work on the baseline distribution, but this mode is of no use on a Windows based platform.

Warning: mail() [function.mail]: Failed to connect to mailserver at "smtp.xxx.sg" port 465, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\xampp\htdocs\confirm\index.php on line 43
